T 0 all whom "it may concern:

Be it known that I, WILHELM BntoMANN,

a subject of the King of Prussia, residing at 23 Bornstrasse, Dortmund, Germany, have invented certain new and useful Improve ments in Apparatus for Tipping Foundry- Ladles; and I do hereby declare the following to be a full, clear, and exact description of the invention. I

This invention consists in an improved apparatus for tipping foundry ladies by means of which the ladle can-be lifted off its carriage and tipped in one movement, so that the liquid metal can be poured outwith the greatest possible uniformity;

, The apparatus consists substantially of two rotary disks or wheels arranged inde pendently of the ladle, between which the ladle supported on its carriage is introduced and by which it is engaged in such a manner that by rotating the said wheels the ladle will be lifted. off its carriage and tipped.

The connection between the ladle and the wheels may be effected by providing the lat ter with open bearings adapted to receive pins arranged on the sides of the upper part of the ladle, and also with an arm, preferably constructed as a connecting bar, adapted to come against the lower part of the front of the ladle. X

By the rotation of, the Wheels the ladle is first lifted ofl' its carriage by means of the bearings engaging with its upper side pins, and then, as the arm on the wheels comes against the front ofthe ladle, the ladle is tipped thereby. The arrangement is preferably such that the spout of the-ladle in tipping, will be situated in the axis of rotation of the two wheels.

in the accompanying drawings, sure 1 is a side elevation, Fig. 2 a front elev. on, and Fig. 3 a plan, of one form of the improved tipping apparatus.

The ladle, a, is supported by its two trunnions, c, on the brackets, d, of the carriage, l).

The ladle is iittcd at its upper edge with a strengthening ring q, provided withpins, r, situated over the trunnions, 0.

Suitable standards, 0, support in bearings, 1, the axles of two wheels or disks, g, which are arranged. at a distance apart suiiicient to allow the carriage b, with the ladle, a, to. be run in between them, as shown in Fig. 2. On the inner sides of the Wheels, 5 there are provided open bearings, 7c, adapted to receive'the upper pins, r, of tho ladle.

rotation of the wheels.

The two wheels are connected together by a bar, n, which is adapted to be brought by the rotation of the wheels against the front of the lower part of the ladle. The two wheels are also connected together n themounted on a shaft, 0, and engaging each in a toothed are extending from a oint, h, to a point, 'i, around the periphery 0 each wl'ieeL;

g. Counterweights, Z,--"are provided it; the purpose of facilitating the tippinget the adle.

The operation of the ap aratus is as follows:

The carriage, 1), wit the ladle, a,'is run from the left (Fig 1). between the two wheels, g, which'fhave been rotated slightly towards the left from the position shownin Fig. 1, so as to bring the hearings in belowthe ins, r, and out of the way of the carriage;

Suitable sto s are provided to hold the car riage with te ladle in the correct position.

l' v'hen this has been accomplishedt e shaft; 0, is rotated by suitable means so as to rotate the wheels, g, in the direction indidatedfby the arrow in Fig. 1.

In this manner, the

bearings, /r, are moved up against the pins, 7,

on the ladle so as to lift the ladle off the supports, 0!. the wheels, 9, the bar, n, is brought to bear against the front of the lower part of the ladle and the latter is thereby caused to turn on the axis of the wheels, g, and thus be tipped.

ably so arranged that the spout of the ladle, when tipped, will be situated in the axis of When empt the ladle is turned back into its trunnion bearon the standards, (1, of the carriage it. Having now particularly described and ascertained the nature of my said invention and in What manner the same is to be per formed I'declare that what I claim is 1- 1. An apparatus for tipping foundry ladies, comprising a pair of suitably supported rotary members adapted to be actuated in unison, means for engaging a ladle between the same, and means in connection with the rotation of said members for lifting said ladle from its support and tipping the same, in combination with a. movable support adapted to convey said ladle to the tipping apparatus, substantially as described.

Then by the continued rotation. of.

The bearings, k, and the bar, n, are prefer- I its ladle and with a transverse bar extending be tween said membersand adapted to impinge against the side of said ladle on the rotation of said members, in combination with means to rotate the latter, substantially-as de scribed. H apparatus for tippin foundry ladies, comprising a pair of suitably supported rotary members adapted to be actuated in unison and provided with open bearings to receive bearing pins on opposite sides of a ladle and ithe transverse bar extending between said members and adapted'to impinge against the side of said ladle on the rotation of said members, in combination with a ladle having side bearing pins and a spout, said bearing; pins, transverse bar and open bearings being so arranged with relation to ,,one another that on rotation of said members the spout is located during the tipping operation substantially on the axis bf; rotation of said members. I v I 4. An apparatus for tippin foundry ladles, comprising a pair of suita 1y supported open bearings carried thereby to receive bearing pins on oppositsides of a ladle, a

transverse bar extending between said members and adapted to impinge against the side of said ladle on the rotation of said members,

in combination with means to rotate the latter, substantially as described.

5. An apparatus for tipping foundry ladles, comprising a pair of suitably supported rotary members adapted to beactuated in unison and provided with open bearings to receive bearing pins on opposite sides of a ladle and with a transverse bar extending between said members and adapted to impinge against the side of said ladle .on the rotation of said members, in combination with a segmental rack on each of said rotary members, gear wheels intermeshing therewith and means for rotating the latter, substantially as described. i
